A golf ball struck by a golfer is allowed to penetrate through the screen such that the struck golf ball disappears from view, thereby increasing the pleasance of golfing environments and a flying image of the golf ball is allowed to be displayed in the simulation image as the struck golf ball disappears from view, thereby further improving the realism of virtual golf, and wherein screen elements which constitute the penetration type screen are prevented from being opened even when golf balls repeatedly pass between the screen elements, thereby improving product reliability. To accomplish this, the penetration type screen includes a plurality of screen elements, each being formed of spandex, the plurality of screen elements being arranged side by side such that the screen elements at least partially overlap each other and are each inclined at a specific angle.

TECHNICAL FIELD

The present invention relates to a penetration type screen for screengolf, and more particularly to a penetration type screen used forso-called screen golf which uses a virtual golf simulation apparatusthat allows golfers to play golf through virtual golf images projectedonto a screen.

BACKGROUND ART

As the interest in golf has recently increased, a virtual golfsimulation system, which is called “screen golf” and which providesrealism allowing users to enjoy golf games indoor as though they playgolf games on actual golf courses, has been introduced.

The virtual golf simulation system is implemented such that the systemprovides, as virtual reality, the same images as those of actual golfcourses in order to provide realism allowing golfers to enjoy golf asthough they play golf games on actual golf courses and also providesrealistic moving golf ball images.

Specifically, an image provided by the golf simulation apparatus isprojected onto a screen provided at a front side of a screen golf booththat forms a specific size of space such that a golfer can enjoy screengolf by striking a golf ball toward the screen while viewing the imageprojected onto the screen.

However, in the conventional screen golf system, golf balls struck bythe golfer are spread in a messy way over the floor of the booth inwhich the screen golf system is installed, deteriorating usersatisfaction associated with golfing environments.

Accordingly, there is a need to develop technology which allows a golfball to disappear from view after the golf ball is struck such that thebooth in which the screen golf system is installed is kept tidy toprovide pleasant golfing environments and which also further improvesthe realism of virtual golf as the struck golf disappears from view.

BEST MODE

An embodiment of a penetration type screen for screen golf according tothe present invention will now be described in more detail withreference to the accompanying drawings.

First, a screen golf system including a penetration type screenaccording to the present invention is schematically described as followswith reference to FIG. 1.

As shown in FIG. 1, the screen golf system is installed in a screen golfbooth 1 having a specific size of space defined by side walls.

A penetration type screen S is attached to a front side of the screengolf booth 1 and a projector 210 that is operated by a golf simulator200 is provided to project a virtual golf simulation image including agolf course, a background, a moving image of a golf ball, and the likeonto the penetration type screen S.

If a golfer steps up to a swing plate 100 provided at the bottom of thebooth 1 and strikes a golf ball placed on a golf mat 110 with a golfclub, the struck golf ball flies toward the penetration type screen S.The golf ball penetrates through the penetration type screen S. Movementof the struck golf ball is detected by a sensor 220 and the golfsimulator 200 implements the detected movement of the struck golf ballas an image and projects the image on the penetration type screen Sthrough the projector 210.

The penetration type screen S is basically formed of a plurality ofscreen elements that are arranged side by side and is implemented suchthat the struck golf ball passes between screen elements.

A buffer is provided at a rear side of the penetration type screen Ssuch that the penetrated golf ball is buffered and drops to a floor ofthe screen golf booth 1. The golf ball which has dropped to the floor ofthe screen golf booth 1 may be conveyed and provided back to the swingplate 100 through a ball conveyor (not shown) provided inside the screengolf booth 1.

The penetration type screen S is described below in more detail withreference to FIGS. 2 to 7.

As shown in FIG. 2, the penetration type screen S for screen golfaccording to an embodiment of the present invention is formed of aplurality of screen elements 10 arranged side by side.

Two frames 20 are provided respectively at upper and lower end portionsof the plurality of screen elements 10 so as to support the array ofscreen elements 10.

Each of the frames 20 may be provided as a single integrated frame thatsupports the entirety of the plurality of screen elements 10 and mayalso be provided as a plurality of sub-frames 21, 22, and 23 into whichthe frame 20 is divided as shown in FIG. 2.

In the case in which the frame 20 is divided into a plurality ofsub-frames (such as sub-frames 21, 22, and 23) such that each of thesub-frames 21 supports partial screen elements (where a combination ofthe sub-frame and the partial screen elements supported by the sub-frameis referred to as a “sub-penetration-type screen”), the penetration typescreen may be configured by arranging a plurality ofsub-penetration-type screens side by side such that, when part of thepenetration type screen has a problem or needs to be washed, it ispossible to separate and replace a sub-penetration-type screencorresponding to the part, achieving ease of work.

On the other hand, a conventional penetration type screen is configuredby arranging a plurality of slats side by side, forming gaps between theslats through which a golf ball can pass. The conventional penetrationtype screen has a problem in that, as golf balls repeatedly pass throughthe gaps between the slats, the sizes of the gaps are graduallyincreased, deteriorating the external appearance, and also has a problemin that an image is not properly projected on the penetration typescreen due to the increased sizes of the gaps.

The penetration type screen S according to the present invention ischaracterized in that the screen elements 10 are arranged side by sidesuch that the screen elements 10 at least partially overlap each otherand are each inclined at a specific angle.

That is, the screen elements 10 are mounted, overlapping each other,such that a part of one screen element 10-1 overlaps a part of anotherscreen element 10-2 and a part of the screen element 10-2 overlaps apart of another screen element 10-3 as shown in FIG. 3. Here, eachscreen element 10 is mounted inclined at a specific angle.

It is preferable that the overlapping portion of each of the screenelements 10 not exceed a half of one screen element and that portions ofthe screen elements 10, each of which is smaller than a half of onescreen element, overlap each other.

FIG. 3 is a cross-sectional view of the arranged screen elements shownin FIG. 2 taken along line I-I in FIG. 2. In FIG. 3, illustration of theframe part is omitted.

It is preferable that, as shown in FIG. 3, the direction of light of theprojector 210 be taken into consideration when the plurality of screenelements 10 is arranged (or installed) such that the screen elements 10overlap each other and are each inclined at a specific angle.

That is, when the projector 210 projects an image obliquely from oneside as shown in FIG. 1, light of the projector 210 travels obliquelytoward the penetration type screen as shown in FIG. 3.

Here, if each of a plurality of screen elements is arranged to beinclined such that a front surface of the screen element faces incidentlight from the projector as shown in FIG. 4, shadows D are created bylight from the projector such that thick stripes are viewed over theentirety of the penetration type screen, which may cause simulationimages not to be smoothly viewed.

Accordingly, it is possible to prevent shadows from being created bylight from the projector by arranging (or installing) the screenelements such that light of the projector is directed toward sidesurfaces of the overlapping portions of the screen elements as shown inFIG. 3.

In addition, by arranging the screen elements such that the screenelements overlaps each other, taking into consideration the direction oflight of the projector as shown in FIG. 3, it is possible tosignificantly reduce the thicknesses of stripes viewed on thepenetration type screen and to allow the stripes to appear uniform,thereby allowing the user not to feel visual discomfort.

If a golf ball is struck toward the penetration type screen in which theplurality of screen elements is arranged such that the screen elementsoverlap each other and are each inclined at a specific angle, the struckgolf ball passes through the penetration type screen while opening anoverlapping portion of screen elements. The opened screen elementsimmediately return to the original state. Here, since each of the screenelements is formed of spandex, the screen elements can elasticallyreturn to an original state and can easily be kept in the original shapeeven when a golf ball repeatedly passes through the screen elements.

Conventionally, elasticity is given to a plurality of slats, which arearranged side by side to constitute a penetration type screen, bymanufacturing each of the slats using non-elastic cloth and providing anumber of means for providing elasticity to end portions of the slats.However, since the slats are lacking in elasticity, there is a problemin that it is not possible to prevent the sizes of the gaps betweenslats from being easily increased as golf balls repeatedly pass betweenthe slats over a long period of time and there is also a risk that theportions of the slats, which are formed of cloth, may be separated fromthe portions thereof which provide elasticity.

The penetration type screen according to the present invention overcomessuch problems by forming each of the plurality of screen elements ofspandex and improves stability (or reliability) by performing fireretardant processing on the spandex material to prevent the spandexmaterial from burning.

Specifically, after fire retardant processing is performed on spandexthread, the fire-retardant-processed spandex thread andfire-retardant-processed silicon may be used to manufacture each screenelement or may be used to manufacture a single large screen and then tocut the single large screen into screen elements.

On the other hand, as golf balls repeatedly pass between the pluralityof screen elements 10 which are arranged such that each screen elementoverlap each other and are each inclined at a specific angle as shown inFIG. 3, the overlapping state of each screen element may not bemaintained.

For example, as golf balls repeatedly pass between the plurality ofscreen elements over a long period of time, a part of one screen elementwhich should overlap another screen element such that the part of theone screen element is located behind the other screen element may bewrongly arranged in front of the other screen element, which may causethe screen elements to be viewed as being partially dislocated whenviewed over the entire penetration type screen.

Accordingly, it is more preferable that a component for performing afunction to maintain the arrangement of the plurality of screen elementsin which the screen elements overlap each other and are each inclined ata specific angle be provided. FIGS. 5 to 8 illustrate an example inwhich such a function is performed through a frame that supports thearrangement of the plurality of screen elements.

FIG. 5 illustrates an example in which a support guide portion supportsthe arrangement of the plurality of screen elements and FIG. 6 is across-sectional view of the sub-frames 21, 22, and 23 shown in FIG. 1taken along line I-I in FIG. 1. FIG. 7 is an exploded view of thesub-frames 21, 22, and 23 shown in FIG. 6 and FIG. 8 is a perspectiveview of the sub-frames shown in FIG. 7.

As shown in FIGS. 5 to 8, it is preferable that support guide portions31 and 32 be formed on the frame 20 so as to support the arrangement ofthe plurality of screen elements 10 in which the screen elements 10overlap each other and are each inclined at a specific angle.

Each of the support guide portions 31 and 32 is formed in a shapecorresponding to the arrangement of the plurality of screen elements 10,in which the screen elements 10 overlap each other and are each inclinedat a specific angle, so as to allow the arrangement of the plurality ofscreen elements 10 to be maintained.

That is, the support guide portions 31 and 32 provide supporting forceto allow the screen elements to quickly return to the original statewhen a golf ball penetrates through the screen elements.

As shown in FIG. 5, the frame 20 may include a first frame portion 20-1which is arranged at a front side of the plurality of screen elements 10and a second frame portion 20-2 which corresponds to the first frameportion 20-1 and is arranged at a rear side of the plurality of screenelements 10 and is coupled to the first frame portion 20-1 to supportthe plurality of screen elements 10.

That is, the frame 20 may be constructed by coupling the first frameportion 20-1 and the second frame portion 20-2 to each other so as tosupport all screen elements.

A first support guide portion 31 having a shape corresponding to thearrangement of the plurality of screen elements 10, in which the screenelements 10 overlap each other and are each inclined at a specificangle, may be formed on the first frame portion 20-1 and a secondsupport guide portion 32 having a shape corresponding to the arrangementof the plurality of screen elements 10, in which the screen elements 10overlap each other and are each inclined at a specific angle, may beformed on the second frame portion 20-2 and the first frame portion 20-1and the second frame portion 20-2 may be coupled to each other to allowthe first support guide portion 31 and the second support guide portion32 to support the arrangement of the plurality of screen elements 10.

FIG. 6 illustrates a state in which the frame 20 is constructed bycoupling a plurality of sub-frames 21, 22, and 23 to each other. Asshown in FIG. 7, it is preferable that the sub-frames 21, 22, and 23respectively include first sub-frame portions 21-1, 22-1, and 23-1,which are arranged at a front side of the plurality of screen elements10, and second sub-frame portions 21-2, 22-2, and 23-2 which correspondrespectively to the first sub-frame portions 21-1, 22-1, and 23-1 andwhich are arranged at a rear side of the plurality of screen elements 10such that the second sub-frame portions 21-2, 22-2, and 23-2 are coupledto the first sub-frame portions 21-1, 22-1, and 23-1 to support theplurality of screen elements 10.

As shown in FIGS. 6 and 7, an end portion X of a first sub-frame portion21-1 of one sub-frame 21 and an end portion Y of a second sub-frameportion 22-2 of another sub-frame 22 may be arranged respectively at thefront and rear sides of the screen elements 10, facing each other, suchthat the end portion X of the first sub-frame portion 21-1 and the endportion Y of the second sub-frame portion 22-2 are coupled to eachother.

In the same manner, an end portion X of a first sub-frame portion 22-1of the sub-frame 22 and an end portion Y of a second sub-frame portion23-2 of another sub-frame 23 may be arranged respectively at the frontand rear sides of the screen elements 10, facing each other, such thatthe end portion X of the first sub-frame portion 22-1 and the endportion Y of the second sub-frame portion 23-2 are coupled to eachother.

Accordingly, there are advantages in that it is possible to configurethe sub-frames such as the sub-frame 21 so as to continuously supportthe screen elements 10 without discontinuous portions between thesub-frames while enabling simple assembly of the sub-frames.

Here, it is preferable that, as shown in FIGS. 7 and 8, a first supportguide portion 31 having a shape corresponding to the arrangement of theplurality of screen elements, in which the screen elements overlap eachother and are each inclined at a specific angle, be formed on the firstsub-frame portions 21-1, 22-1, and 23-1 and a second support guideportion 32 having a shape corresponding to the arrangement of theplurality of screen elements, in which the screen elements overlap eachother and are each inclined at a specific angle, be formed on the secondsub-frame portions 21-2, 22-2, and 23-2 and the first sub-frame portions21-1, 22-1, and 23-1 and the second sub-frame portions 21-2, 22-2, and23-2 may be coupled to each other to allow the first support guideportion 31 and the second support guide portion 32 to support thearrangement of the plurality of screen elements.

In addition, it is preferable that, as shown in FIG. 8( a), the firstsupport guide portion 31 include first inclined surface portions 31 asuch that inclined front surfaces of the plurality of screen elements 10are secured to and supported by the first inclined surface portions 31a, and first risers 31 b which are formed at end portions of the firstinclined surface portions 31 a such that one side surfaces of the screenelements are secured to and supported by the first risers 31 b.

It is also preferable that, as shown in FIG. 8( b), the second supportguide portion 32 include second inclined surface portions 32 a such thatinclined rear surfaces of the plurality of screen elements 10 aresecured to and supported by the second inclined surface portions 32 a,and second risers 32 b which are formed at end portions of the secondinclined surface portions 32 a such that the other side surfaces of thescreen elements are secured to and supported by the second risers 32 b.

Accordingly, the structure of the first support guide portion 31including the first inclined surface portions 31 a and the first risers31 b and the structure of the second support guide portion 32 includingthe second inclined surface portions 32 a and the second risers 32 b arecoupled to each other to form the structure in which the screen elements10 overlap each other and are each inclined at a specific angle.

FIG. 9 illustrates a state in which a plurality of support members 40 isarranged at specific intervals at the rear sides of the plurality ofscreen elements 10 such that the plurality of support members 40 crossesthe plurality of screen elements 10.

It is preferable that the support members 40 be formed of a highlyelastic substance such as spandex or rubber. Both end portions of thesupport members 40 may be fixed to wall surfaces or alternativelyadditional structures may be provided such that the support members 40are fixed to the structures.

Accordingly, the support members 40 support the plurality of screenelements such that the screen elements can return to the original shapeseven when golf balls pass between the screen elements.
